The proposedresearch questions the sensoryimaginary, especiallysound, of travelers who visited the Souks of the medina in the 19th century. The restitution of this ambiantal memory is used to participate in the recon-sideration of the urban and architectural heritage of this highly historic space, the Souks, by sonic ambiances. Our ambiantal approach is based on quantitative and qualitative (notion of sonic effect) content analysis of the 19th century texts.

The proposed study concerns the characterization of sound ambiances produced by the traditional architectural device gannariyya and its contemporary reproduction, implanted in two different neighboring urban fabrics of the capital Tunis. Thus, we adopted an ambiantal multidisciplinary method based on two approaches. First, quantitative approach involves observations in situ and the processing of audio signal measurements and sound recordings taken simultaneously from both sides of the gannariyya. Second, qualitative approach implies interviews with users in addition to recognize their perception of the sound phenomenon. Our field of study is the traditional medina of Tunis and the neighboring modern city. The results collected through measurements, frequency analysis and interviews, show that both types of device filter the sound signal differently. They also reveal that new building materials are responsible of this gap.
